: I have a 1965 Martin D-35 in excellent condition. What’s its approximate value today? 1965 was the first year for the D-35. Martin made 207 D-35s that year, all with Brazilian rosewood backs and sides. Condition is the most important factor in appraising a guitar. "Condition" also includes the degree of originality, whether any repairs have been done (or are needed) and if so, the quality of the repair. Guitars with Brazilian backs and sides are also especially desirable. Anyone who claims to be able to give you a definitive appriaisal via email, sight unseen, is not to be trusted. Having said that, a 1965 D-35 in "excellent" original condition ("excellent" has become a term of art in the vintage guitar world, and encompasses a wide range), that doesn’t need repairs or regular maintenance (neck reset, refret) is, per the Blue Book of Acoustic Guitars, worth at least $3000.
